Rock Flow Dynamics released the second update in 2022 of the tNavigator software package. Version 22.2 is now available to users. Updates and improvements affected the simulator kernel, AHM and Uncertainty module, Geology and Model Designer, PVT Designer, Well, and Network Designer.

Key new features in 22.2:

In the Simulator kernel:

• For compositional models in E3 format, the option of rock wettability dependence on the adsorbed solid concentration is now supported.
• For compositional models, the simulation of acid-base reactions by setting equilibrium constants in the water phase is now supported.
• The option of blockwise specification of the power parameter for the Corey/LET RP correlations is now supported.
• It is now possible to modify endpoint scaling properties in blocks with fractures.
• Results upscaling for further export in binary format (GRID, EGRID, INIT, UNRST, and UNSMRY files) is now available. Grid scaling is performed in accordance with the algorithm of the COARSEN keyword.

In the Simulator GUI:

• Production calculation and display of results by branches of multilateral wells are now supported.

In the Assisted History Matching and Uncertainty module:

• It is now possible to display an initial probability density function of variables, cumulative distribution function (CDF) and quantiles on a histogram.

In Geology and Model Designers:

• The following new attributes have been added for series objects in the Crossplot tab: symbol size, symbol type and opacity.

In Geology Designer:

• A 3D-Grid may be created based on a source one, which will be cut by the specified faults (the Create Grid by Faults Cutting calculation).
• The amplitude between fault lines may be set using a pre-created fault attribute (the Correct Fault Lines Amplitude by Attribute calculation).

In Model Designer:

• The interface to set the parameters of chemical reactions is now available.
• In FS Simulator, a multicomponent model can now be used to calculate the flow when injecting fluids and proppants of several types.
• In FS Simulator, it is now possible to calculate simultaneous propagation of fractures from multiple perforations located at a small distance from one another in a specified wellbore range.
• In FS Simulator,  the liquid and proppant flows, the liquid composition and the well diameter are now used to calculate the pressure losses in injection.

In Well Designer:

• It is now possible to calculate IPR correlation parameters as a function of bottomhole and reservoir pressure.

In Network Designer:

• It is now possible to set temperature zones for pipes.
• A new Valve object has been added to allow/prohibit fluid backflow.
• It is now possible to set a maximum flow limitation for an automatic choke. To calculate the diameter of the automatic choke, simultaneous setting of a flow limitation and a control type for inlet/outlet pressure is now supported.
